Solution steps

5 arctan (1) - 1

Use the following trivial identity:

arctan (1) = \frac{π}{4}

arctan (1)

x 0 \frac{3}{3} 13 arctan (x) 0 \frac{π}{6} \frac{π}{4} \frac{π}{3} arctan (x) 0^{\circ} 3 0^{\circ} 4 5^{\circ} 6 0^{\circ}

= \frac{π}{4}

= 5 \cdot \frac{π}{4} - 1

Simplify

5 \cdot \frac{π}{4} - 1 : \frac{5 π}{4} - 1

5 \cdot \frac{π}{4} - 1

Multiply

5 \cdot \frac{π}{4} : \frac{5 π}{4}

5 \cdot \frac{π}{4}

Multiply fractions:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{π 5}{4}

= \frac{5 π}{4} - 1

= \frac{5 π}{4} - 1
